Young Percy Averhoff returns to Hamburg after a five-year stay abroad and finds that his parents have already found a bride for him. The young man however has his own ideas, and rebelliously answers a contact ad in which a girl is looking for a young man as a companion for a car trip to Southern Germany. Soon the two of them are on the way. What Percy doesn't know is that the damsel is none other than the girl his parents have chosen for him.
